Quick answer
A very common beginner question in Bangladesh: is a serum the same as a moisturiser, and do you need both? Short answer: they do different jobs, and yes, most routines use both. Here is why.

- A serum is a lightweight, concentrated liquid that delivers active ingredients (vitamin C, niacinamide, hyaluronic acid, etc.) to *treat a concern* — brightening, oil control, hydration, anti-aging. See the serum guide.
- A moisturiser is a thicker cream/lotion that hydrates and seals — it locks water in and protects the skin barrier. See which moisturiser.
Think of it as: serum = *treatment*, moisturiser = *protection*.
Do you need both?
Usually yes. A serum treats the concern but does not seal moisture well; a moisturiser protects but does not carry strong actives. Together they work best.
- Order: cleanser → (toner) → serum → moisturiser → sunscreen (AM).
- Apply serum on slightly damp skin, then lock with moisturiser.
Exceptions
- Very oily skin in humid weather can sometimes use a hydrating serum + light gel moisturiser, or a moisturiser that doubles up — see the oily routine.
- Very dry skin needs both, plus a richer moisturiser — see the dry-skin routine.
- On a tight budget, prioritise: gentle cleanser + moisturiser + sunscreen first, then add a serum for a specific concern.
